manifold of any internal combustion engine,

lt is well known that when starting from rest any internal combustion engine, ywhich is supplied with a volatile fluid for fuel, much cranking is with a combustible ,usually necessary before-` thel engine are supplied. mixture. Even when an f extra sup ly of fuel is sprayed into the-1ntake manifold of the engine much trouble',

' the air is also experienced' in proper mixture. In have sought to pr quickly getting a roviding my invention 1 uce a combined Vaporizer and priming pump which would givej a combustible mixture almost immediately upon t-urning the'. crank'over. To this end: have so disposed the priming' pump in rej lation to the 'vaporizer that the fluid, as it is sprayed from the the engine is priming pump, before cranked, is caused to be well distributed over the vaporizer, so that when 1 fluid is proportioned combustib e mixture.l t i is drawn therethrough the saidE thoroughly vaporized and there is? drawn. into the engine c linder, a pro erly l, of t-he vaporizein also well known. thatit is more diicult to start an internal combustion engine in` cold Weather than in warm weather. come this difficulty I have whereby the temperature o the vaporizer may be kept practically the same in cold as well as warm weather. These and many other advantages of my invention will be apparent to those skilled in the art from the accompanying drawings and following description.

In the drawings, forming part of this specification, like characters of reference refer to like parts throughout the several views of which:

In the drawings the numeral the combined'vaporizer and priming pump 6A is a carbureter and 7 the intake manifo of any internalcombustion engine.

8 1s the fuel nozzle of the carbureter with l 10 is the float chamber and 11 the ioat dis Josed therein.

he volatile fluid is supplied to the carbureter at 12 and-a portway 13 conducts the fluid1 frim the float chamber 10 to the fuel nozz e` 5 represei-itsI and 9 is the choketube.

14 is the easing1 of the 'vaporizer which is providedV at its upper end with a head 15 and atits lower end with a similar head 16 which are secured respectively to the intake manifold 7 and the .'carbureter l6.

Disposed within'the vaporizer body 14 are l atomiziirig.` sections 17 preferably formed of a corrugated sheet of copper 18 and a Hat sheet of copper 19l said corrugated sheet a te and said il sheet the vform of a spiral (see Fig. 3), thus prolongitudinal ,passageis eft between each ing rolled togetherA in i section 17 and disposed in the center of said spaces or baffle plates '22 and 23. The baille plate 22 is of solid material at its outer periphery but is provided'with an o en cen-y tral ortion 24 formed in any suita le way. The baille plate 23 is provided with a closed central portion 25 but a space 26 is left between its outer periphery and the casing 14 Thus 4the outwardly bv the baffle by the baffle 'plate 22.

caused to be thrown plate 23 and inwardl Disposed preferab Vvaporizer 5 and extending up. through the baille plates 2 2and 28 and the atomizing sections 17 is the priming pump 27.

28 is the cylinder of the priming pump' which is preferably held in place by the said baille plates and the atomizing sections 17, and 29 the piston of the saine. VAt the lower end of the elinder is iitted a vapors are y in the center of the l plug 30 which is provide with a ball check valve; 31 arranged to close the portway 48 n said plug. In the lower end ofv the piston 29 is, preferably loosely mounted,I a needle valve 32 which is engageable with a seat provided inthe cylinder 28 and thus closes the aperture 33 which leads from the ball check valve to the interior of the cylinder. Provided in the center' of the piston 29 is a portway 34. This portway is connected at its lower end with the interior of the cylinder by the portways 35 and 36 and extending into the vaporizer from the said portway 34 near the upper end thereof is a plurality of apertures 45 through which the volatile iluid is sprayed. Between the portway 34 and the portway 35 is disposed a ball check valve 37. The upper end of the piston is provided with a plug which closes the upper' end of the portway 34. This plug is provided with lugs 39 to which is pivotally secured a link 40. y

In the head 15 is removably secured an operating crank bearing 41 which rotatably carries the operating crank-42. .This crank y is provided with a crank pin'43 which is priming pump.

`engageable with the upper end of the link 40 when the bearing 41 is put into place. At lever 44 is secured to the outer end of the crank 42 and provides means whereby the piston 29 may be moved upwardly. The upper end of the piston 29 is provided for a portion of its length with a reduced peripheral diameter and this portion has disposed theren-a spiral spring 46. One end of the said spring bears against the shoulder formed by the reduced diameter of the piston and the other end bears against a bearing nut 47 which is preferably screwthreaded into the upper end of the cylinder 28 and which also forms an upper bearing for the piston 29. Y

Leading from some convenient the float chamber 10 vor the portway 13 of the carbureter 6 is a pipe 49 which conducts the volatile fluid to the cylinder 23 of the A stop-cock 50 is inserted at some convenient place in the pipe 49 whereby the supply of volatile fluid to the priming pump may be shut ofi' if desired.

Obviously, it is not necessary to have the pipe' 49vrunning outside of the carbureterbut it may, if desired, be extended up through the choke tube-9er any other suitable means may be employed for conducting the volatile fluid to the priming pump. i

51 is a jacketwhich is secured to the heads 15 and `16 and is provided with an inlet and outlet 52 and 53. Either hot water or hot air may be passed through this K jacket, thereby making it possible to keep the vaporizer at a proper working temperature.'

When 1t 1s desired to start an internal combustion engine, which is tted with my vaporizer, the lever 44 on the operating crank 42 of the priming pump is operated by any suitable and conveniently arranged means, which raises the piston 29 and the point in A supply of the volatile fluid is thereby drawn through the pipe 49 or its equivalent, portway 48, past the ball check valve 31, through the portway 33 and into the cylinder 28. When the said piston is lowered. by the spring 46 the ball check valve 31 will be forced closed and the ball vcheck Valve 37 will be lforced open by the pressure of the fluid as it is being forced up through the portways 35 and 3G and into the portway 34. As the said piston is being lowered the fluid contained in the cylinder of the priming pump will be forced out of the piston 29 and sprayed onto the upper atomizing section 17. Now as the engine is cranked the cylinders of the same will cause air to be drawn up through the choke tube of the carbureter and the atomizing sections 17 of the Vaporizer. As this air is drawn through the upper atomizing section 17 it picks up and mixes with the molecules of fluid which have been previously scattered over this section and a combustible mixture is thereby formed which is immediately, drawn into the cylinder of the engine and ignited, thus making the starting of the engine very easy. When the engine has been started the volatile lluid is then supplied by the carbureter in the usual manner but the spray of fluid, as it leaves the needle valve of the carburetor, is made to pass through the atomizing sections 17 of the vaporizer 5 and in so doing it is thor oughly broken up and mixed with the air, thus making a better and more thoroughly vaporized combustible mixture than is ordinarily supplied to internal combustion engines. The baiile plates 22 and 23 prevent the mixture from passing straight through the vaporizer and these add greatly to the Vaporizing process. When the priming pump piston 29 is in its lower position it will be seen that the needle valve 32 will be when the said piston is operated.

Instead of inserting the vaporizer and priming pump between the carburcter and the intake manifold, obviously, manifold may be provided with an extra outlet to which the vaporizer and priming pump'may be separately attached and thus used solely for priming purposes. When nected to the manifold in the usual manner.

Obviously, the atomizing sections may be heated by means of a plurality of radiating pipes passing through the said sections and carrying, in circulation, heated water or any other suitable liquid.

Obviously, if` desired, the carbureter (l may be made an integral part of the head 116 of my vaporizer and many other dcneedle valve 32 secured to its lower end. tailed modifications may be made from the through the apertures 45 in the upper end l seated, thus stopping the flow of volatile fluid through the pipe 49 at all times but thus arranged the carbureter will be con` the intake i device herein shown and described without departing fromfthe spirit of my invention and I do not Wish to be limited to the exact embodiment herein shown and described.
